M.2 drive backplanes
Use the section to understand the cable routing for the M.2 drive backplanes.
The server supports one of the following M.2 drive backplanes:
![]() | |
1 | M.2 x4 non-RAID SATA/NVMe 2-bay backplane |
2 | M.2 x1 RAID NVMe 2-bay backplane |
3 | M.2 RAID SATA/NVME 2-bay backplane |
M.2 x4 non-RAID SATA/NVMe 2-bay backplane
